Further to above...

Did portsnap update this afternoon. kBuild reported warning:
------
In file included from 
/usr/ports/devel/kBuild/work/kBuild-0.1.9998/src/kmk/make.h:67:
/usr/include/sys/timeb.h:42:2: warning: "this file includes 
<sys/timeb.h> which is deprecated" [-W#warnings]
-----

  emulators/virtualbox-ose-kmod (4.3.24) and emulators/virtualbox-ose 
(4.3.24) are still blocked by error given above.

I may not be the only one affected here. A quick google search dug up 
this thread:
https://gist.github.com/tangentstorm/af2c97d89e194b3356c3

User indicated exact same error using gcc4.8.4 build.
